DEVICE FOR SHARPENING RAZORS.

SPECIFICATION forming part of Letters Patent No. 382,027, dated May l,1888.

Application filed December 7, 1887. Serial No. '257,1r`0, (No model.)

To all whom it 'ma/y concern.-

Be it known that I, PETER JOHAN Glinsan, of Rothsay, in the county ofWilkin, State of Minnesota, have invented certain new and usefulImprovements in Devices for Sharpening Razors, of which the following isa specification.

As heretofore done, the operation of sharpening a razor is one whichrequires considerable skill for its successful accomplishment.

My invention consists, generally, in a device the use of which enablesany person unskilled in the art to quickly and successfully sharpen arazor; and the invention consists, further, in the construction andcombination hereinafter described, and particularly pointed out in theclaims.

In the drawings forming a part of this speciication, Figure 1 is a planview of my device having the upper part of the handle removed.

h Fig. 2 is a side elevation of the same, indicat-` Fig. 3 is a sectionon line y y of Fig. 1.

ing by dotted lines the position of the razor. Fig. 4 is a sectionalview on the line fr x of Fig. 1, showing my device applied to therazor-strop and the relative position of the parts when it is drawntoward the operator. Fig. 5 is a similar View showing the parts whenmoved in the opposite direction.

In the drawings, 3 represents ahan dle,which may be made of any suitablematerial and in any suitable form. It is preferably made of two partssecured together by screws or rivets 5 and having on their inner sidesrecesses 7, thus leaving a space or opening in the interior of thehandle. its inner end is located a block, 9, which is connected with thesides of the handle by a pivot, l1. A shaft, 13, is, preferably by meansof screw-threads, held by its rear end in the block 9 and is adapted toturn slightly therein. It extends forward, passes through,and isjournaled in another block, 15, beyond which it carries a smallcog-wheel, 17. The wheel 17 engages a rack-bar, 18, which is secured tothe forward end of the handle, as shown in Fig. 3. A tube, 19, having aportion of its surface removed to adapt it to receive and hold therazor-blade, is fastend to the shaft 13. It is provided at its forwardend with the projections 23, which form a support for the handle In thisopening and near A'of the razor. A, frame, 25, formed, preferably, ofwire and of substantially rectangular form, has its inner end connectedto the block 15 and its outer end extends under the outer end of therazorsupport, forming a bearing therefor. A wire, 27, is secured to oneside of this frame, extends at right angles across the frame near therear end thereof, passing under the outer end ofthe shaft 13 near thepoint where the razor-holder 19 is joined to it, and then extendslengthwise of the frame 25, near the other side thereof, as shown inFigsl and 5. A spiral spring, 29, is preferably arranged upon the wire27, having one end secured thereto and its other end bearing against theframe 25. This spring tends to throw the other end of the Wire up,thereby bringing that portion of the wire which passes under the shaft13 against the under side of that shaft.

In Figs. et and 5 I have shown a portion of a strop, 30, such as isordinarily used by barbers for sharpening razors. This strop, when thetool is in use, passes under the razorholder and between one side of theframe 25 and the free end of the wire 27. lIhe razor 3l is placed inposition, preferably, by having the back of the blade inserted into thetube 19, with' the edge of the blade projecting therefrom, as shown inFigs. Ltand 5. The handle end of the razor is held between theprojections 23, as shown in Fig; 2. The parts being in this position,the handle of the tool 3 is grasped by the hand of the operator, and theother hand will usually be employed to grasp one end of the strop 30,the other end of which is generally fastened to a nail or other device.The tool being then drawn toward the operator, the block 9 will turnupon its pivot, the shaft 13' will be thrown as far as possible to onesideof the slot 7, and as it is moved in this direction the engagementof the pinion 17 With the rackbar 18 causes the shaft 13 and the tube orrazorholder 19 to be turned upon their axes,thereby bringing one side ofthe edge of the razor upon the strop, as shown in Fig. 4, where it isheld as long as the tool is moved in this direct-ion. When the tool hasbeen drawn as far as desirable in this direction, its motion is reversedand it is moved in the opposite direction. The first part of themovement in the opposite di- IOG rectiou causes the shaft 13 to swing tothe opposite side of the recess in the handle, and as it moves, thepinion or cog-wheel 17, moving over the rack-bar 18, causes therazor-holder 19 and razor carried by itto beturned about ahalf-revolution, thereby bringing the other side ofthe edge of the razorupon thestrop 30, as shown in Fig. 5, in which position it remains untilthe movement of the tool is again reversed.

' Suttieient friction is created between the strop, the wire 27, and theframe 25 to cause the frame to remain stationary when the move mentofthe tool is reversed until the position of the razor-holder has beenreversed. The wire 27, actingin conjunction with the frame 25, forms africtional clamp, which holds the tool with sucient friction upon thestrop. I do not conne myself, however, to the details of construction ofthe frame and the frictionclamp, as the construction of these parts maybe varied Without changing the operation of the tool. By using this toolany person can sharpen a razor. No special skill is required for theoperation, as the razor is brought in proper position upon the strop toaccurately sharpen it.

The tool may be used with any other kind of strop or hone insubstantially the same way, in which case there will be sufficientfriction between the frame 25 and the surface of the hone to cause therazor-holder to be reversed in the same manner herein described.

I claim as my invention- 1. The combination, in a razor Sharpener,

with the handle 3, provided with the recess 7, of the shaft 13,pivotally secured at its inner end to the handle within said recess andadapted to be turned on its axis as itis swung upon its pivot, and therazor-holder secured to said shaft, substantially as described.

2. The combination, with the recessed handie 3, provided with therack-bar 18, of the shaft 13, pivotally secured Within the recess ofsaid handle and provided with the pinion 17, engaging said rack-bar, andthe razor-holder 19, secured to said shaft, substantially as described.

3. 'The combination, with the recessed handle3,provided with therackhbar18,of the shaft 13, pivotall y secured Within said recessedhandle and provided with the pinion 17. engaging said rack-bar, therazor holder 19, secured upon said shaft, and the frame 25, secured uponsaid shaft and extending upon opposite sides of said razor-holder.

4. The combination, with the recessed handle3, provided with therack-bar 18, ofthe shaft 13, pivotally secured within said handle andprovided with the pinion 17, engaging said rack-bar, the razor holdersecured to said shaft, the frame 25, and the spring friction clamp 27,all substantially as described.

In testimony whereof I have hereunto set my hand this 30th day ofNovember, 1887.
